3.44x10^2
you move the decimal over to get a single digit number with change. The number of times you move the decimal is the number for the 10 power
Answer:
6,1,2
Explanation:
_Ag + _N2 => _Ag3N
LHS RHS
Ag=1×6=3 Ag=3×2=6(Balanced)
N=2×1=2 N=1×2=2(Balanced)
coefficient=6,1,2
Answer:
1.5 mol
Explanation:
Step 1: Given data
- Volume of argon gas: 33 L
- Standard temperature: 273.15 K
Step 2: Calculate the moles corresponding to 33 L of argon at standard temperature and pressure (STP)
At STP, 1 mole of argon gas occupies 22.4 L.
33 L × 1 mol/22.4 L = 1.5 mol
Answer:
Explanation:
For this question we have to start with the <u>reaction</u>:
Now, we can<u> balance the reaction</u>, so:
With this in mind, we have to start with the amount of 
. The first step is to <u>convert from grams to moles</u>. For this, we need to find the molar mass of . If we check the periodic table we will find the atomic masses for Ag and H; H: 1 g/mol and A: 32 g/mol, so:
(1*2)+ (32*1) = 34 g/mol.
Now we can <u>calculate the moles</u> of :
With the moles of we can calculate the moles of 
if we check the <u>molar ratio in the balanced equation</u>, 
, so:
With the molar mass of we can <u>convert from moles to grams</u> (Ag: 107.86 g/mol, S: 32 g/mol), so:
(107.86*1)+(32*2)=247.80 g/mol
I hope it helps!
