Answer:
The difference is the combining vowel
Explanation:
The Combining form needs the vowel to form, that is:
root word + combining vowel = combining form
<u>Root word</u>:
A root is a word that does not have a prefix in front of the word or a suffix at the end of the word. The root word is the main lexical unit of a word and a family of words, which carries the most significant aspects of semantic content and cannot be reduced to smaller components
<u>Combining form</u>:
Training process of words from two or more roots or simple words.
When the word includes a cultured base and a patrimonial base, we will consider derived word. For example, hypermarket, bi-monthly
Answer:
D. Halogens
Explanation:
All elements in these groups have 7 valence electrons, meaning their electronegativity is the highest among the elements.
Answer:
a. 0.026 M
Explanation:
Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:
Molarity = n/V
Where;
n = number of moles (mol)
V = Volume of solution (L)
Based on the information provided;
V = 23.2mL = 23.2/1000 = 0.0232 L
n = ?
To get the number of moles of KHP, we use the formula:
mole = mass/molar mass
mole (n) = 0.123/204.2
mole (n) = 0.0006024mol
Molarity = n/V
Molarity = 0.0006024 ÷ 0.0232
Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2
Molarity = 6.024/2.32 × 10^(-4--2)
Molarity = 2.59 × 10^-2
Molarity = 0.026 M
Answer:
The third line
Explanation:
The first one us wrong because they're not all found inside,electron is outside.
The second one is wrong as I explained previously.
Lastly the fourth line is wrong because protons are found in the nucleus.
Answer:
Explanation:
In one mole of liquid HF , no of molecules is 6.02 x 10²³.
Each molecule forms two hydrogen bonds on an average so no of hydrogen bonds per mol ih HF is
2 x 6.02 x 10²³.
= 12.04 x 10²³ .
In water no of hydrogen bonds per molecule of water is 4 . So in one mole of water no of hydrogen bonds is
4 x 6.02 x 10²³.
= 24.08 x 10²³ .
