Stable if they have a full outer shell. 8 electrons in their outer shell
Answer:
Would not have Crankyosis, but Carrie's the allele for it.
Explanation:
If the disease is recessive, someone with the Aa genotype wouldn't the disease, but could potentially pass it down to offspring.
Answer:
Energy of compressed string-potential energy (because it has ability to do work).
Energy of coal -potential energy (because it has ability to do work).
Energy of guitar string when plucked- kinetic energy(because the string is moving).
Energy from a flashlight when on - kinetic energy (because the light waves are in motion).
Answer:
28g/mol
2 moles of nitrogen are present
Explanation:
The molar mass is defined as the mass of a chemical when 1 mole of this substance is present and is used to convert mass of the substance to moles or vice versa. Is widely used in stoichiometry problems.
1 atom of nitrogen has a molar mass of 14g/mol. N₂(g) -The molecule that contains 2 atoms of nitrogen- has a molar mass of 28g. That is 28g/mol.
56g of N₂ are:
56g * (1mol / 28g) =
<h3>2 moles of nitrogen are present</h3>
Answer:
The correct answer is the third option.
Explanation:
Moles of nitrogen tribromide = 40 mol
Moles of sodium hydroxide = 48 mol
According to reaction, 2 moles of nitrogen tribromide reacts with 3 moles of sodium hydroxide, then 40 mol of nitrogen tribromide will react with:
This means that in order to completely react with 40 moles of nitrogen tribromide we will need 60 moles of sodium hydroxide.
But according to the question we only have 48 moles of sodium hydroxide which is less than the 60 moles of sodium hydroxide which indicates that sodium hydroxide is present in a limited amount and nitrogen tribromide is present in an excess amount.
So, the limiting reagent is sodium hydroxide, hence the correct answer is the third option.
