Answer: The volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is LiOH.
We are given:
Putting values in above equation, we get:
Thus the volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml
<em>réponse</em>: <em>verdadero</em>
<em>Explication</em>:
Answer:
A. 70.0 kpa
Explanation:
Given
Pressure = 525.4 torr
Required
Convert to kPa
From standard unit of conversion;
Multiply both sides by 525.4
<em>(Approximated)</em>
<em>From the list of given options, option A is the closest answer after 525.4 torr is converted to its kpa equivalent</em>
6.79 x 10⁶
<h3>Further explanation </h3>
Scientific Notation consists of 2 parts
1. the first part: the first digit followed by the decimal point
2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point
To add/subtract, the exponents must be the same and then add/subtract the coefficient
- convert the largest exponent
- subtract the coefficients
Water has highest flow rate
