2. Balance the equation below, and answer the following question: What volume of chlorine gas, measured at STP, is needed to com
Juliette [100K]
Balanced equation: 2Na(s) + Cl₂(g) ---> 2NaCl(s)

when we have STP conditions, we can use this conversion: 1 mol = 22.4 L

first, we have to convert grams to molecules using the molar mass, and then use mole to mole ratio from the balanced equation. 

molar mass of Na= 23.0 g/mol
 ratio: 2 mol Na= 1 mol Cl₂ (based on coefficients of balanced equation)

calculations:

6.25 g Na ( \frac{1 mol Na}{23.0 g} ) ( \frac{1 mol Cl_2}{2 mol Na} ) ( \frac{22.4 L}{1 mol} )= 3.04 L

Which actions increase the strength of an electromagnet? Question 5 options: Increase the number of coils and decrease the stren
SVEN [57.7K]

An electromagnet is a device in which, by electric current, the magnetic field is produced. Increase the number of coils and increase the strength of the current, thus, increasing the strength of an electromagnet.

The correct option is B.

<h3>What is an electromagnet?</h3>

An electromagnet is a device that consists of a magnetic core encircled by a coil, through which an electric current is carried to magnetize the core.

Wherever controllable magnets are required, such as in devices where the magnetic flux must be adjusted, reversed, or switched on and off, an electromagnet is utilized.

Thus, the correct option is B, increasing the number of coils and increasing the strength of the current.

Meteorologists use weather balloons to carry weather instruments high into the atmosphere. When it is first released at Earth’s
ahrayia [7]

<span>The balloons volume as it rises increases because at higher altitude external pressure is lower, so the air molecules inside the balloons tends to expand more to attain mechanical equilibrium, where the external pressure and internal pressure are equal. Unlike when the balloon is on the ground, external pressure is great so the gas molecule cannot push the walls of the balloon so it is like underinflated.</span>
