There are 6.33 × 10²⁵ hydrogen atoms in this solution in total.
<h3>Explanation</h3>
- There are two hydrogen atoms in each water molecule.
- There are three hydrogen atoms in each ammonia molecule.
2.10 × 10²⁵ water molecules and 7.10 × 10²⁴ ammonia molecules will contain
hydrogen atoms in total.
I think the correct answer is A. Dichlorosilane has a formula of SiH2Cl2. As we can see, for every mole of this compound there will be two atoms of chlorine, two atoms of hydrogen and one atom of silicon. There are 3 different types of atoms involved. And all of this makes up a compound.
Answer:
Explanation:
The changes in properties from metals to non-metals on a periodic table can be measured and determined by the metallicity or electropositivity of elements.
Metallicity is a measure of the tendency of atoms of an element to lose electrons.
a.
Down a periodic group, metallicity increases.
b.
Across a period from left to right electropositivity or metallicity decreases.
Metals are found in the left part of periodic table and the most reactive metal sits in the lower left corner. Non-metals are towards the right side of the table.
328 % means 0.328 g of KCN in 100 g of solution
0.328 g of KCN ---------> 100 g of solution
1120 * 10^-3 g of KCN ------> (100 / 0.328) * 1120 * 10^-3
= 341 g of solution
Answer:
<h2>1 ) substances that produce hydrogen atoms in solution.</h2>
Explanation:
A swedist scientist Savante Arhenius give the theory of behaviour of Acid-bases. According to Arhenius ,Arhenius Acid compound produce hydrogen ion or proton upon adding in aqueous solution . Acid are molecular compound that have higly polar covalently bonded ionizable hydrogen atom. HCL is a polar covalently bonded and gas at room temperature and noormal pressure . Upon addition of HCL in water cause ionization ,water breaks into chloride ion and hydrogen ion , in this reaction chlorine gain bond pair electron , while hydrogen ion or proton attached with water . chlorine gain bond pair electron due higher electronegativity than hydrogen and hydrogen loose their electron due to less electronegativity and become hydrogen ion ,these hydrogen ion attached with water to form hydronium ion . Hydronium ion is polyatomic ion .
- Ionization of HCL in water
- formation of polyatomic hydronium ion after HCL ionization in water ,where hydrogen ion attached to water and form polyatomic ion.
