Answer:
Here's what I get
Explanation:
In a single replacement reaction, one element must displace another element from its compound.
Thus, we must consider the reactivity series, because an element lower down in the series cannot replace one that is above it.
In a double replacement reaction, the cations change partners with the anions. All we need consider are the solubilities of the new cation-anion partners.
The cofficent is 2 for diphosphorus trioxide
The first thing you need to do with problem of this kind is to write the chemical equation. This would help you in calculations later. First, convert how many moles are there in 1.75g of carbon dioxide. Then, from the chemical equation you will know how many moles of sodium bicarbonate formed with 1 mole of carbon dioxide. Then convert the moles of sodium bicarbonate to grams using the molecular weight of the compound. You now have your answer.
Answer:
2.3 atm
Explanation:
-7.50°C = 265.5 K
38°C = 315 K
(2.72)(265.5)=(pressure)(315)
pressure = 2.3 atm
Answer:
Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom. Their movement generates an electric current and causes each electron to act like a microscopic magnet
