The volume of the key is 0.8 mL.

An object that floats on water will displace its own volume. In the same vein, an object that sinks in water will displace its own volume.

Thus, in order to find the volume of an object that sinks in water, measure the volume of water that it displaces.

In this case, the water displaced by the key was measured 3 times. The average of the 3 readings will give the volume of the key.

Volume of the key = 0.7 + 0.8 + 0.9/3 = 0.8 mL

Answer:

the squid population could decrease, because the tuna population is increasing and they would eat more squid, so the dolphin population would also decrease because there would be less squid to eat, and because there are less squid the herring population would increase.

In trophic webs, there is an equilibrium between species until a change occurs. The increase in tuna's population causes a decrease in dolphins' and squids' populations, and an increase in herring's one.

------------------------

To answer this question, let us first review some theoretical framework.

The trophic web is a relationship process between different organisms, through which occurs transference of energy.

The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.  

As it is a web, all organisms are equilibrated until a change occurs.

When the change affects any of the involved links, there can be a cascade effect on the web.

A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.

Now, let us analyze the exposed example.

We know that,

We need to figure out what is the cascade effect caused by the increase in the tuna population.

We know that tuna and dolphins compete for food items -squids-.

An increase in the number of tuna individuals means a higher competition pressure for dolphins.

The more tuna there are, the more squids they eat, and the less food available there is for dolphins.

Since there are not enough squids for dolphins, their population decreases in size.

Dolphins are negatively affected by tuna's increase.

**** Tuna population increases  ⇒  Dolphins population decreases ****

Tuna applies a significant predation pressure on squids, which are their main source of food.

The more tuna there are, the more squids they eat.

Squids probably can not reach sexual maturity or do not get to successfully reproduce, because they are eaten by tuna.

So squids population is negatively affected by the tuna population increase.

**** Tuna population increases  ⇒  Tuna population decreases. ****

Since squids feed on herring, any change in squids' population size affects herrings directly.

When the squids' population decreases in size, the herring population increases. More fishes get to survive and successfully reproduce.

The predation pressure of squids on herring decreases.

The herring population is positively affected by the squids' population decrease.

*** Squids population decreases  ⇒  Herring population increases. ***

Summing up, the cascade effect is as follows,

Answer : Yes, a precipitate form when a solution of calcium chloride and a solution of mercury(I) nitrate are mixed together.

The net ionic equation will be,

\(2Hg^{+}(aq)+2Cl^{-}(aq)\rightarrow Hg_2Cl_2(s)\)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

\(CaCl_2(aq)+2HgNO_3(aq)\rightarrow Ca(NO_3)_2(aq)+Hg_2Cl_2(s)\)

The ionic equation in separated aqueous solution will be,

\(Ca^{2+}(aq)+2Cl^{-}(aq)+2Hg^{+}(aq)+2NO_3^{-}(aq)\rightarrow Hg_2Cl_2(s)+Ca^{2+}(aq)+2NO_3^{-}(aq)\)

In this equation, \(Ca^{2+}\text{ and }NO_3^-\) are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

\(2Hg^{+}(aq)+2Cl^{-}(aq)\rightarrow Hg_2Cl_2(s)\)

Taking into account the definition of net ionic equation, a precipitate of Hg₂Cl₂ is formed when a calcium chloride solution and a mercury (I) nitrate solution are mixed.

The net ionic equation is a chemical equation for a reaction that lists only the species that participate in the reaction.

In other words, an ionic equation is a chemical equation where electrolytes in aqueous solution are written as dissociated ions. Usually this is a salt dissolved in water, where the ionic species are followed by (aq) in the equation, to indicate that they are in aqueous solution.

The balanced equation will be:

CaCl₂(aq) + 2 HgNO₃(aq) → Ca(NO₃)₂(aq) + Hg₂Cl₂(s)

where (aq) means aqueous and (s) solid.

Taking into account that:

The total ionic equation in separated aqueous solution will be:

Ca²⁺(aq) + 2Cl⁻(aq) + 2 Hg⁺(aq) + 2NO₃⁻(aq) → Ca²⁺ + 2NO₃⁻(aq) + Hg₂Cl₂(s)

A spectator ion is an ion that appears both as a reactant and as a product in an ionic equation.

Spectator ions can be either cations (positively charged ions) or anions (negatively charged ions).

When writing a net ionic equation, spectator ions found in the original equation are ignored. Thus, the total ionic reaction is different from the net chemical reaction.

In this case, Ca²⁺ and NO₃⁻ are the spectator ions because they appear unchanged in both the product and the reagent. So these ions cancel out by writing the net ionic equation and you get:

2Cl⁻(aq) + 2 Hg⁺(aq) → Hg₂Cl₂(s)

Since Hg₂Cl₂ is an insoluble salt, it will precipitate.

Finally, a precipitate of Hg₂Cl₂ is formed when a calcium chloride solution and a mercury (I) nitrate solution are mixed.

If working for an oil company and directed to start drilling for oil or gas in a given area, you would want to gather a variety of types of evidence to support this decision. Some types of evidence to consider include:

Geological evidence: You would want to study the geology of the area, including the type of rock formations present, the depth of the rock layers, and the history of the area's geologic activity. This information can help you determine if the area has the potential for oil or gas reserves.

Geophysical evidence: You would want to use various geophysical tools to gather information about the subsurface of the area, including magnetic surveys, seismic reflection surveys, and gravity surveys. These tools can help you determine the location and size of potential oil or gas deposits.

Well data: You would want to review well data from nearby areas, including the depth of the well, the type of rock formations encountered, and any oil or gas reserves found. This information can help you predict the potential for similar reserves in the area.

Environmental data: You would want to review environmental data, including air and water quality, to assess the potential environmental impact of drilling in the area.

Economic data: You would want to review economic data, including the cost of drilling and the potential revenue from oil or gas production, to determine if drilling in the area is financially feasible.

By gathering and analyzing these types of evidence, you can make a more informed decision about whether or not to direct engineers to start drilling for oil or gas in a given area.

Answer:

conducting thorough geological surveys to identify areas with potential oil or gas reserves. This would involve analyzing rock formations, seismic data, and other geological features to determine the likelihood of oil or gas being present. Additionally, I would recommend reviewing historical drilling records and production data to identify areas that have already shown promise. It is important to ensure that drilling operations are conducted in a safe and environmentally responsible manner to minimize potential harm to the surrounding ecosystems and communities.
