Answer:
Answer:- 1467 K
Solution:- It asks to calculate the kelvin temperature of the light bulb. Looking at the given info, it is based on ideal gas law equation, PV=nRT.
Answer:
C. Graph C
Explanation:
We have a mixture of water and ice.
At 0 °C they are at equilibrium.
water-to-ice rate = ice-to-water rate
Next, we lower the temperature to -3 °C — just slightly below freezing.
The water will slowly turn to ice.
The water-to-ice rate will be slightly faster than the ice-to-water rate.
The purple bar will be slightly higher than the blue bar.
Graph C best represents the relative rates
A. is wrong. The ice-to-water rate is faster, so the water is melting. The temperature is slightly above freezing (say, 3 °C).
B. is wrong. The two rates are equal, so the temperature is 0 °C.
D. is wrong. The water-to-ice rate (freezing) is much greater than the ice-to-water rate, so the temperature is well below freezing( say, -10 °C).
These particles are called as molecules and Can be further divided into smaller particles called atoms and these molecules are made up of same kind of atoms
Answer:
electroplating
Explanation:
Electroplating means coating a metal into zinc to protect from rust
Sacrificial protection is the protection of iron or steel against corrosion by using a more reactive metal
Answer:
14.125
Explanation:
If my calculations are right.
- there are 44.0 moles in co2
- +20.0
- which equals 64
- there are 78.125 moles in O2 so just subtract it by 64 which gives you
- 14.125
MOLE CALCULATION
divide the mass of the material by its molar mass. The molar mass of a substance is the mass in grams of one mole of that substance.
