Answer:
2 C2H6 + 7 O2 = 4 CO2 + 6 H2O
Explanation:
The Bold Numbers are what you should put. This is balanced
Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution.
Answer:
8.8 cm³
Explanation:
Data given:
volume of Liquid = 0.0088 L
convert volume to Cubic centimeters
Solution:
There are number of unit in which volume can be measured
As
Liter is unit of volume represented by L
Cubic centimeters represented by cm³
liter is larger value then cm³
Now to convert L to cm³
As we Know
1 L = 1000 cm³
So
Apply unity formula
1 L = 1000 cm³
0.0088 L = x cm³
Do Cross multiplication
x cm³ = 0.0088 L x 1000 cm³ / 1 L
x cm³ = 8.8 L.cm³ / 1 L
x cm³ = 8.8 cm³
So,
0.0088 L of liquid = 8.8 cm³

Answer:
97 000 g Na
Explanation:
The absortion (or liberation) of energy in form of heat is expressed by:
q=m*Cp*ΔT
The information we have:
q=1.30MJ= 1.30*10^6 J
ΔT = 10.0°C = 10.0 K (ΔT is the same in °C than in K)
Cp=30.8 J/(K mol Na)
If you notice, the Cp in the question is in relation with mol of Na. Before using the q equation, we can find the Cp in relation to the grams of Na.
To do so, we use the molar mass of Na= 22.99g/mol
Now, we are able to solve for m:
=97 000 g Na
