Answer:It is a plant
Explanation:
A new organism is discovered. It is multicellular, heterotrophic, and does move on its own. The organism belong to Kingdom Animalia.
What do you mean by heterotrophs ?A heterotroph is an organism that obtains energy and nutrients from other plants or animals. The term is derived from the Greek words hetero, which means "other," and trophe, which means "nourishment."
Fungi are multicellular, heterotrophic eukaryotes with chitinous cell walls. Kingdom Plantae contains autotrophic organisms with cellulosic cell walls, whereas Kingdom Animalia contains heterotrophic organisms without cell walls.
Animalia is a kingdom of multicellular, heterotrophic organisms. This kingdom includes humans and other primates, as well as insects, fish, reptiles, and a variety of other animals.
Thus, The organism belongs to Kingdom Animalia.

. I am described as being conductive, malleable, shiny, and reactive with HCl. I am one of the most reactive elements. I turn black within seconds when I am exposed to air. If someone drops water on me, I will explode. When I do explode I send off characteristic purple-red (violet) flame. Who am I?
Answer:
Potassium
Explanation:
Most reactive metal in the reactivity series
The element in the question is referred to the alkali metal which is known as Potassium
Potassium is a highly reactive metal and reacts with Hydrochloric acid to
form a salt known as Potassium chloride and hydrogen gas.
Hcl + K ⇒ Kcl₍s₎ + H₂₍g₎
Potassium has a white color but when it reacts with water it explodes and
gives out a purple-red color as a result of the high excitation of electrons.

A 35 kg child is standing in a 70 kg boat resting on the water. The child jumps forward, away from the boat, pushing with a force of 500 N. After the jump, the boat moves backward.
What does this scenario show?
A. The boat does not exert a force to balance the 500 N force, causing the boat to move.
B. The water creates a frictionless surface, causing the boat to move without an action force.
C. The boat has a greater mass than the child but reacts to an action force.
D. The water beneath the boat absorbs the 500 N force but keeps the boat afloat.
Answer:
A
Explanation:
the boat does not have a force to counter act the boys it must give which means it moves cause it is one something that is not as dense as the boy (I THINK)

B) What mass of sodium hydroxide could be obtained by heating a 20 mL sample of this solution to dryness?
C) If 30 mL of the solution were mixed with sufficient water to produce 480 mL of a more dilute solution, what would be the concentration of the dilute solution?
D) If 200 mL of the more dilute solution were then mixed with 100 mL of the more concentrated solution, what would be the concentration of the mixed solution?
Answer:
(A) 0.80 M
(B) 0.64 g
(C) 0.050 M
(D) 1.6 M
Explanation:
(A)
Convert 4.0 g to moles with molar mass. Convert 125 mL to L.
4.0 g x (1 mol/39.998 g) = 0.100 mol
125 mL x (1 L/1000 mL) = 0.125 L
Molarity = mol/L
Molarity = 0.100 mol/0.125 L = 0.80 M
(B)
Find moles of NaOH with the molarity you just found. And convert 20 mL to L.
Molarity = mol/L
0.80 M = mol/0.020 L
mol = 0.016
Convert moles to grams with molar mass.
0.016 mol x (39.998 g/1 mol) = 0.64 g
(C)
You know the molarity of a NaOH solution (Part A). 30 mL initial volume and 480 mL final volume are given. Dilution question so use the dilution formula.
M1V1 = M2V2
(0.80 M)(30 mL) = (M2)(480 mL)
M2 = 0.050 M
(D)
Dilution question again, use the dilution formula.
M1V1 = M2V2
(0.80 M)(200 mL) = (M2)(100 mL)
M2 = 1.6 M

Answer:
m = 204.16 grams
Explanation:
Given that,
No. of moles, n = 3.49
Molar mass of NaCl, M = 58.5 g/mol
We need to find the mass of 3.49 moles NaCl. We know that,
[tex]n=\dfrac{m}{M}\\\\m=n\times M\\\\m=3.49 \times 58.5\\\\m=204.16\ g[/tex]
So, there are 204.16 grams in 3.49 moles NaCl.
