Answer:
Explanation:
Hello,
In this case, for the given chemical reaction, we first identify the limiting reactant by noticing that due to the 1:1 mole ratio for magnesium to iodine the reacting moles must the same, nevertheless, there are only 2.68 moles of magnesium versus 3.56 moles of iodine, for that reason, magnesium is the limiting reactant, so the theoretical turns out:
Thus, we compute the percent yield as:
Best regards.
Answer:
D.Salad
Explanation:
A mixture is a substance that combines two or more substance that are physically combined. A mixture can be easily seperated by a physical means . A mixture is the combination of various substances that are not chemically combined .Examples of mixtures are cake and salad . The cake contains various substances like egg, flour and sugar. This mixture can be easily separated into it individual entities by a physical means .
Base on the option the only mixture among the option is salad . Salad is a a mixtures that combines substances like tomatoes , fruits and vegetable. The individual substances that makes up the salad can be easily separated.
Sugar is a compound . Water is a compound as it contains two elements and potassium is an element.
The partial pressure of carbon dioxide is 75 torr.
<h3>What is Dalton's theory?</h3>
Dalton's theory of gas states that total pressure of the mixture of gas sample is equal to the sum of the partial pressure of all the gases present in that sample.
Given that,
- Total pressure of mixture = 825 torr
- Partial pressure of Nitrogen = 600 torr
- Partial pressure of oxygen = 150 torr
- Partial pressure of carbon dioxide = ?
On putting values, we get
Partial pressure of carbon dioxide = 825 - (600 + 150) = 75 torr
Hence Partial pressure of carbon dioxide is 75 torr.

To form a 2+ ion, you need to lose two negatively charged electrons. Because metals have relatively empty outer shells, they lose electrons. Metals are on the left hand side of the table, and in order to lose two electrons, you need to have two electrons to start with. The groups of the table are based on the number of electrons an element has in the outer shell, so Group 2 metals will lose two electrons to gain a 2+ charge
