What is the definition of a Macronutrient?
Because Mg and O2 are both elements, no bonds were broken during the formation of MgO.
True or false
Answer:
false
Explanation
The chemical bonds were broken when creating the compound MgO.
What are two ways to increase the strength of an electromagnet?
Add more turns of the wire to the solenoid.
Increase the amount of current that passes through the wire.
Decrease the amount of current that passes through the wire.
Decrease the turns of the wire to the solenoid.
Answer: Two ways to increase the strength of an electromagnet is
Add more turns of the wire to the solenoid.
and
Increase the amount of current that passes through the wire.
Explanation: Factors that affect the strength of electromagnets are the nature of the core material.
How many atoms of Br are there?How many atoms of Br are there?
Answer:
8
Explanation:
There are 8 atoms of Br because there are two molecules of 4 atoms of Br. 4 x 2 = 8.
Answer: 1 mol Br contains 6.022×1023Br atoms;its mass is 79.90 g.
Explanation:
: I mole or bromine refers to 6×10^23 molecules of bromine. But 1 molecule of bromine has 2 atoms. Hence the atom count will be exactly twice.

Explanation:
How do air masses flow?
from regions of low pressure to high pressure
it depends on the time of the day
from regions of high pressure to low pressure
whichever way the wind blows
How do air masses flow?
from regions of high pressure to low pressure
.
In general, cold air masses tend to flow toward the equator and warm air masses tend to flow toward the poles.
1. Define a solution and explain why it is considered a Homogeneous Mixture.
Answer:
They contain two or more substances mixed together.
Explanation: That's all I know about it. I know the other answer is way better but I hope this helps
How are electromagnets temporary?
A.) They are only magnetic when an electric current runs through them.
B.) They are only magnetic when a gravitational wave runs through them.
C.) They are only magnetic when near a lodestone.
D.) They are only magnetic for two weeks.
Such magnets are called temporary magnets. An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.
So A
How many atoms of S are there?
Giving brainliest and thanks to best answer <333 :>
Answer:
C
Explanation:
radiation from the sun first warms the outer atmosphere (trophosphere)
convection(aka just heat moving through gas or liquid) brings the warmth down lower
conduction heats the ground

Answer:
Lavoisier reacted mercury with oxygen to form mercuric oxide
Fill in the blank:
Tree roots speed up ____ by creating and widening cracks in rocks! Tree roots slow down ____ by holding sediments in place so they're not transported away as quickly.
Answers to pick:
1) Weathering, erosion
2) Erosion, weathering
Answer:
Weathering, Erosion
Explanation:
Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.
Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.
Hope this helps

there are blanks in the picture. what kind of winds are being asked about?
Only about half of the Sun’s energy that reaches Earth is absorbed. The rest is reflected back into space. Which surface is LEAST likely to absorb solar energy and why?
Select one:
a. rock, because it is solid
b. snow, because it is white
c. water, because it is liquid
d. asphalt, because it is black

How do you think other galaxies might be similar or different from the Milky Way Galaxy?
Answer:
Going off of our own galaxy, one could assume that the universe is filled with other planets, moons, and stars. The interesting thing to me would be the shape of the Milky Way. It would be interesting to see how other galaxies have formed. As in, are they spherical, oblong, in the shape of a square?
There are also endless possibilities for undiscovered metal alloys in space, which is very exciting to me. The idea of space mining has been brought up many times before, but if there are new and useful metals, precious gems, or minerals that are yet to be discovered outside of the milky way, they could help restore Earth.
