Answer:

31.36 L of chlorine gas will react with 56 g of calcium.

Explanation:

Ca + Cl_2\rightarrow CaCl_2

Mass of calcium = 56 g

Moles of calcium gas = \frac{56 g}{40 g/mol}=1.4 moles

According to reaction, 1 mole of calcium react with 1 mole of chlorine gas.

Then 1.4 mol of calcium wiull react with :

\frac{1}{1}\times 1.4 = 1.4 mol chlorine gas

At standard temperature and pressure. 1 mol of gas occupies 22.4 L of volume.

Then 4.1 moles of chlorine gas will occupy :

22.4 L\tmes 4.1 =31.36 L

31.36 L of chlorine gas will react with 56 g of calcium.

The balanced chemical reaction is:

<span>Ca + Cl2 =  CaCl2
</span>
We are given the amount of calcium metal to be used for this reaction. This will be the starting point for the calculations.

56 g Ca ( 1 mol Ca / 40.08 g Ca) (1 mol Cl2 / 1 mol Ca) ( 22.414 L Cl2 / 1 mol Cl2 ) = 31.32 L Cl2 gas produced from the reaction

Human activities, like burning fossil fuels and deforestation, have greatly contributed to global warming. In this discussion as
Travka [436]

Answer

Africa

Explanation:

Burning fossil fuels and deforestation is disturbingly heightened in Africa with almost no viable measure taking to control it's effect. No effective programs are presently in place to control excessive tree falling used for herbs, firewood, charcoal business and a whole lot. Below standard carbon rating PMS are in high circulation with fumes, carbon monoxide is full abundance in the atmosphere. Presently, all these unchecked activities have resulted into unexplainable excessive increase in temperatures, breeding neck twisting diseases, severe skin infections, dehydration and increase diabetes. Drought has eaten up landlocked cities in Nigeria and Central Africa. Infact farmers have lost count of the usual natural cycle of rainfall and the beginning of each farming season due to this essential evil of climate change

Suppose a scientist proposes a plan to destroy all bacteria on Earth in order to get rid of diseases caused by bacteria. Explain
dimulka [17.4K]
This would not be a good idea because bacteria is everywhere and function as a part of out everyday lives. Starting off with animals, many animals rely on bacteria to digest their food so many animals would begin to die off. Ecosystems would fail due to nitrogen not being able to cycle.
Without bacteria biological waste would build up causing a drop in population, eventually going extinct.
Basically, the balance of nature between humans, animals, and plants would no longer exist.

Consider the following specific heats: copper, 0.384 J/g· ◦C; lead, 0.159 J/g· ◦C; water, 4.18 J/g· ◦C; glass, 0.502 J/g· ◦C. Wh
Roman55 [17]

Answer:

The correct answer is

2. Water

Explanation:

The specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree. It is connected to the capacity of the substance to retain heat as well as the rate at which it will cool down or heat up when exposed to a specific amount of heat loss or heat supplied. A substance with a low heat capacity such as iron will cool down or heat up more quicker than a substance with a high heat capacity such as water.

From the list of substances water has the highest heat capacity, (4.18 J/g) as such it will retain heat for the longest period of time.
