Answer:
The answer is
<h2>0.89 atm </h2>Explanation:
To convert from kPa to atm we use the conversion
101.325 kPa = 1 atm
If
101.325 kPa = 1 atm
Then
90.23 kPa will be
We have the final answer as
<h3>0.89 atm</h3>Hope this helps you
Which section of the reaction represents the products? A) a B) b C) c D) d
2 answers:
Answer: D) d
Explanation:
Reactants of a chemical reaction is defined as the substances which take part in a chemical reaction and undergoes a chemical change. Reactants are written on left side of the arrow. Part labelled as a.
Thus barium hydroxide and ammonium nitrate are reactants of the reaction.
Products are defined as the substance which are formed at the end of the chemical reaction.Products are written on the right side of the arrow. part labeled as d.
Thus barium nitrate, ammonia and water are products of the reaction.
Heat is the necessary condition for the reaction. Labeled as b.

Answer:
In water hydrogen bonding formed between partially negative oxygen and partially positive hydrogen atoms.
Explanation:
Hydrogen bond is a partially electrostatic attraction between hydrogen (H), which is bonded to a more electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F), and another adjacent atom bearing a lone pair of electrons.
In water molecule hydrogen and oxygen have difference in electronegativity, due to which dipoles are form. One is partial positive on hydrogen atom and other is partial negative on oxygen atom. The electrostatic attraction occur between two oppositely charged poles which is known as hydrogen bonding.
