The balanced chemical equation for reaction of and is as follows:
From the balanced chemical equation, 2 mol of reacts with 1 mol of .
First calculating number of moles of as follows:
On rearranging,
Here, M is molarity and V is volume. The molarity of is given 0.274 M or mol/L and volume 155 mL, putting the values,
Since, 1 mol of reacts with 2 mol of thus, number of moles of will be .
Now, molarity of is given 0.305 M or mol/L thus, volume can be calculated as follows:
Therefore, volume of is 278.5 mL.
Answer:
Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon and the Sun, plus the rotation of the Earth. Tides are caused by the gravitational pull of the moon and sun. High and Low tides are caused by the moon. Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other.

Answer:
Explanation:
This experiment converts mechanical energy to electrical energy. The movement of the magnet in and out of the coil is mechanical energy and the current induced in the circuit as a result of the magnet movement is electrical energy.
It should be noted that generally electromagnetic induction as described by faraday (and indeed the experiment described in the question) involves the transformation of mechanical energy into electrical energy. It's application is used in transformers, electric motors and generators.
Answer:
8.98*10^23 molecules CO2
Explanation:
The molar mass of CO2 is 44.0 grams/mol. If we convert 65.8 grams of CO2 into moles, 65.8g CO2 / 44.0g CO2 then we get about 1.49 moles of CO2. We know there are 6.02*10^23 molecules in a mole, so we would just multiply 1.49 mol CO2 * 6.02*10^23 = 8.98*10^23
Within a period, the atom size decreases with increasing group number (from left to right), since the nuclear charge and the number of external electrons increase within the period, but the number of shells does not. The electrons are more strongly attracted to the nucleus and are therefore closer to the nucleus.
