Answer:
Mass = 365.45 g
Explanation:
Given data:
Number of moles of HNO₃ = 5.8 mol
Mass of HNO₃ = ?
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of HNO₃ = 63.01 g/mol
by putting values,
Mass = 5.8 mol × 63.01 g/mol
Mass = 365.45 g
The formula for lead chromate is PbCrO4. This is because the Pb is the lead part- it is the first in the formula with one lead atom. Next is CrO4- chromate. It has a negative charge (-2) and it stands for one chromium atom and four oxygen atoms.
Answer:
The metals in this group are lithium, sodium, potassium, rubidium, cesium, and francium. The gas hydrogen is also put in this group because it shares similar reactivity with the alkali metals.
I don't know if this is what you wanted or not sorry if it isn't
Answer:
yeah they dream in weird shapes mostly I think. unless they weren't born blind then they dream normally I think
Answer:
Excess Reagent = oxygen
Explanation:
Limiting reagent: The substance that is totally consumed when the reaction is completed.
Excess reagent: The substance left after the limiting reagent is consumed completely
The balanced chemical equation for formation of water is as follow:
This means when 2 moles of hydrogen reacts with 1 mole of oxygen, 2 moles of water is produced.
Hence the ratio in which hydrogen and oxygen gas reacts is 2:1
Now if 2 mole hydrogen require 1 mole of oxygen ,then 4 mole hydrogen need 2 mole of oxygen.
or
Here 5 mole of oxygen is reacting but only 2 mole is required .
Oxygen is in excess.
