Gatorade is an example of a homogenius or heterogenius mixture?

Answer:

[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> 2 KNO_{3} + PbCrO_{4}[/tex]

Reactions:

[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> KNO_{3} + PbCrO_{4}[/tex]

Explanation:

In the reaction, the CrO4(Chromate)  is a compound NO3(Nitrate) is a compound as well.

Ignore the number in front of the reaction first, calculate how many K, Cr, O, Pb and N in the equation for both left and right side.

Left side:   K=2, Cr=1, Pb=1, N=2, O=10

Right side: K=1, Cr=1, Pb=1, N=1, O=7

So we need 3 more oxygen, 1 more nitrogen and 1 more potassium on the right.

If we add a 2 in front of KNO3, there will be 2 potassium, 2 Nitrogen and 6 oxygen, which the reaction complete.

Conclusion:

[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> 2 KNO_{3} + PbCrO_{4}[/tex]

Answer:

[tex]\boxed {\boxed {\sf 5.1 \ mol \ H_2O}}[/tex]

Explanation:

To convert from representative particles to moles, Avogadro's Number: 6.02*10²³, which tells us the number of particles (atoms, molecules, etc.) in 1 mole of a substance.

We can use it in a ratio.

[tex]\frac {6.02*10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Multiply by the given number of molecules.

[tex]3.1*10^{24} \ molecules \ H_2O*\frac {6.02*10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Flip the ratio so the molecules of water cancel out.

[tex]3.1*10^{24} \ molecules \ H_2O*\frac {1 \ mol \ H_2O}{6.02*10^{23} \ molecules \ H_2O}[/tex]

[tex]3.1*10^{24} *\frac {1 \ mol \ H_2O}{6.02*10^{23} }[/tex]

[tex]\frac {3.1*10^{24} \ mol \ H_2O}{6.02*10^{23} }[/tex]

Divide.

[tex]5.14950166113 \ mol \ H_2O[/tex]

The original number of molecules has 2 significant figures: 3 and 1, so our answer must have the same. For the number we calculated, that is the tenth place. The 4 in the hundredth place tells us to leave the 1.

[tex]5.1 \ mol \ H_2O[/tex]

There are about 5.1 moles of water in 3.1*10²⁴ molecules of water.

Explanation:

because the sun is at the center of the universe the planet orbit the sun its basically a simple answer so if you need more help im right here

The sun and the planets are part of the solar system. The sun is in the center of the system, and the planets revolve around it. Thus, option C is correct.

A solar system is a part of the Milky Way galaxy that includes the planets, stars, sun, moon, asteroids, etc. The Sun is the star that is fixed at the center of the system.

The planets are not fixed and revolve in orbit around the sun and rotate on their axis. The sun and planets are made up of gases and have different atmospheres.

Therefore, option C. sun is at the center around which the planets revolve.

The nucleus controls the cells activities

Answer:

Within a group trend

Explanation:

The atomic radius of atoms generally increases from top to bottom within a group trend. As the atomic number increases down a group, there is again an increase in the positive nuclear charge.  As the atomic number increases within a period, the atomic radius decreases.

Answer:

The Northern Hemisphere is tilted toward the Sun in summer is the correct answer.I hope this helps

Explanation:

Day turns into darkness as the Earth spins, and summer turns into winter when the Earth completes its whole cycle. Therefore, the Northern Hemisphere is tilted toward the Sun in summer. The correct option is option B.

The circular motion of an item about its center is referred to as rotation. Things can spin in a variety of ways.  When a round, three-dimensional object rotates around an imaginary line inside of its center, it is a relatively common type of rotation. This focal point is known as an axis.

The Earth's rotation and revolution effect wind patterns, temperature, ocean currents, and precipitation, which together determine our local weather and the planet's overall climate. the Northern Hemisphere is tilted toward the Sun in summer.

Therefore, the Northern Hemisphere is tilted toward the Sun in summer. The correct option is option B.
