Answer:
Heat, Q = 45 J
Explanation:
We have,
Mass of aluminium is 5 g
The temperature is raised from 22°C to 32°C.
The specific heat of aluminium is 0.90 J/g°C.
It is required to find the heat are needed to raise the temperature.
The heat required to raise the temperature is given by :
So, 45 J of heat are needed to the temperature of 5.0 g of aluminum from 22°C to 32°C.
Answer:
The chemical formula for ammonium hypochlorite is NH4ClO.
The chemical formula for ammonium nitrate is NH4NO3.
Explanation:
These two are correct
Answer:
When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon).
Explanation: pls mark brainliest :))
Answer: I think it could be Decomposition
Explanation: I think is composition because decomposition starts by being together and ends up as two
Answer:
Both have the same amount of particles.
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ particles.
This implies that 1 mole of Hydrogen contains 6.02×10²³ particles. Also, 1 mole of oxygen contains 6.02×10²³ particles.
Thus, 1 mole of Hydrogen and 1 mole of oxygen contains the same number of particles.
