Answer:

the transfer of energy because eating is gaining energy from a source, so the energy from that source is being transfer to the animal.

The transfer of energy is achieved when eating and feeding exists. Chemical processes may emit or absorb chemical energy.

The ability of a physical process to carry out work is known as energy. It's crucial to remember that simply because energy exists doesn't indicate that it is always ready to do tasks. Thermal energy, sometimes known as heat, is generated when atoms or molecules move. It may be thought of as temperature-related energy.

This energy results from the location of an item. For instance, a ball resting on a table possesses potential energy in relation to the ground because of the influence of gravity. Chemical processes may emit or absorb chemical energy. It is created by atoms and molecules establishing or breaking chemical bonds.

Therefore, the transfer energy is achieved when eating and feeding exists.

Answer:

Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic

Explanation:

Minerals are formed due to chemical composition by rocks are pressured into their formed from dirt and naturally hard things.

The statement that represents a distinguishing difference between rocks and minerals is as follows:

Thus, the correct option for this question is B.

A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition, and atomic structure. Rocks are generally made up of two or more minerals, mixed up through geological processes.

Minerals are definitely formed due to chemical composition by rocks being pressured into their formation from dirt and naturally hard things. A rock is an inorganic and a solid naturally-formed substance without any chemical composition or atomic structure.

A mineral is also a solid, inorganic, substance as that like a rock which has a definite crystalline structure as well as chemical composition. Rocks form, break down and move through the rock cycle.

Therefore, the correct option for this question is B.

Answer:

1 / 2 of her money would be left

Explanation:

Tammy spent 2/5 of her savings on a watch. She then spent 1/6 of the remainder on a bag. What fraction of her money did she have left?

Taking the question bits by bit;

Tammy spent 2/5 of her savings on a watch

Amount Spent = 2/5

Remainder = 1 - 2/5 = 3/5

She then spent 1/6 of the remainder on a bag

Amount Spent = 1/6  *  3/5 = 1/2  *  1/5  = 1 /10

Total amount spent = 2/5 + 1 /10 =   (4 + 1 ) / 10 = 5 / 10 = 1 / 2

Amount left = 1 - 1 /2 = 1 / 2

Explanation:

they are classified in eight steps namely doma!n, k!ngdom, phylum, class, order, family, genus, and spec!es

but sometimes we do not include doma!n

if you want to name an organism you use both the genus group and the spec!es group

Example:

The scientific name for humans like us is h0m0 sap!ens

H0m0- This is our genus group

sap!ens- This is our spec!es group

sorry for using the exclamation mark it means i

Answer:

43.76 g = 0.04376 Kg

Explanation:

The equation of the reaction is given as;

H2 + Cl2 --> 2HCl

From the equation;

1 mol of Cl2 produces 2 mol of HCl

Converting to mass;

Mass = Number of mol * Molar mass

Cl2;

Mass = 1 mol * 70.906 g/mol = 70.906 g

HCl;

Mass = 2 mol * 36.458 g/mol = 72.916 g

This means;

70.906 g of Cl2 produces 72.916 g of HCl

x g of Cl2 would produce 45g of HCl

70.906 = 72.916

x = 45

x = 45 * 70.906 / 72.916

x = 43.76g

Answer:

Explanation:

follow the rule of "a weak acid can't make a stronger acid and weak base can't make a stronger base(it's pretty accurate for acid/salt reactions/replacemnts)" the last reactions won't work, but the second to last one will be kbr+pb(no3)2-> kno3 + PbBr2 (this is unballanced.) the first reaction will work. the second one i'm not too sure tbh, but i think it won't work since barium hydroxide's a weak base and if it were to react it would make koh, a super strong base

Answer:

3Ba(OH)2 + 2K3PO4 ----> 6KOH + Ba3(PO4)2

2KBr + Pb(NO3)2  ------> 2KNO3 + PbBr2

H3PO4 + 3KCl -----> K3PO4 + 3HCl

Answer: 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.

Explanation:

The balanced chemical reaction is :

[tex]N_2+3H_2\rightarrow 2NH_3[/tex]

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]  

[tex]\text{Number of moles of nitrogen}=\frac{853.42g}{28g/mol}=30.479moles[/tex]

According to stoichiometry:

1 mole of [tex]N_2[/tex] react with = 3 moles of [tex]H_2[/tex]

30.479 moles of [tex]N_2[/tex] will react with=[tex]\frac{3}{1}\times 30.479=91.437moles[/tex] of [tex]H_2[/tex]

 Mass of [tex]H_2[/tex] =[tex]moles\times {\text {Molar mass}}=91.437mol\times 2g/mol=182.87g[/tex]

Thus 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.
