Answer: 0.8541 grams of HCl will be required.
Explanation: Moles can be calculated by using the formula:

Given mass of
= 0.610 g
Molar mass of
= 78 g/mol

Number of moles of
= 0.0078 moles
The reaction between
and HCl is a type of neutralization reaction because here acid and base are reacting to form an salt and also releases water.
Chemical equation for the above reaction follows:

By Stoichiometry,
1 mole of
reacts with 3 moles of HCl
So, 0.0078 moles of
will react with
= 0.0234 moles
Mass of HCl is calculated by using the mole formula, we get
Molar mass of HCl = 36.5 g/mol
Putting values in the equation, we get
Mass of HCl required will be = 0.8541 grams
Answer:
pH = -1
Explanation:
A solution of 10 mol·L⁻¹ HCl is very acidic.
HCl is a strong acid, so it dissociates completely in water and
To get the pH, you take the negative logarithm of the hydronium ion concentration.
So, a pH = -1 represents a very acidic solution.
Answer:
5.89 g × 10⁶ μg
Explanation:
Step 1: Convert 5.00 scruples to grains
We will use the conversion factor 1 scruple = 20 grains.
5.00 scruple × 20 grain/1 scruple = 100 grain
Step 2: Convert 100 grains to ounces
We will use the conversion factor 1 oz = 480 grains.
100 grain × 1 oz/480 grain = 0.208 oz
Step 3: Convert 0.208 oz to grams
We will use the conversion factor 1 oz = 28.34 g.
0.208 oz × 28.34 g/1 oz = 5.89 g
Step 4: Convert 5.89 g to micrograms
We will use the conversion factor 1 g = 10⁶ μg.
5.89 g × 10⁶ μg/1 g = 5.89 g × 10⁶ μg

Answer:
The base pairs are what makes up an individual's genes.
Check below for further explanation.
Explanation:
The base pairs A, C, T and G are the basic molecules which makes is the DNA of individual.
The genes of an individual which determines the phenotypical expressions found in an individual such as eye colour, height, etc, are functional units found in the DNA.
Therefore, the arrangement of the base pairs determines the gene present in an individual and thus, the individual's phenotype.
