Answer:
0.0100M of AgNO3 contains 0.0100M of Ag+
Explanation:
AgNO3 when ionized yields Ag+ and NO3-. This means that the amount of AgNO3 in solution is equivalent to the amount of Ag+ and NO3- in that same solution.
1M of AgNO3 solution produces 1M of Ag+
1M of AgNO3 solution produces 1M of NO3-
This occurs because of the complete ionization of AgNO3 in solution, allowing complete dissolution of the compound.
Answer: It's only one proton in the middle of the red circle there's nothing outside it.
Explanation: I'm not sure sorry :|
hope this helps
16 I think but I could be wrong lol
The answer to your question is : no.of moles of Si = 43/atomic mass of Si = 43/28.1 = 1.53
according to reaction 3 moles of Si gives 1 mole of Si3N4
so 1.53 mole of Si will give 1.53/3 = 0.51 mole of Si3N4
molar mass of Si3N4 = 140.28 g/mole
it means that 1 mole of Si3N4 = 140.28 g
so 0.51 mole of Si3N4 = 0.51 X 140.28 = 71.543 g
There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.
<h3>What is the mass of a substance?</h3>
The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.
To determine the energy from the 8g of carbohydrate, we have:
= 8g × 4 kcal/g (the corresponding calories of food type)
= 32 kcal
The energy from 2g of fat = 2g × 9 kcal/g
= 18 kcal
The energy from protein is calculated as:
= 140 kcal - 32 kcal - 18 kcal
= 90 kcal
The required mass of the protein in grams is:
= 22.5 grams
Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.
