- Competition for space is lowest in waters along the equator.
- Equatorial waters provide some of the clearest water for symbiotic algae to pro
pce energy,
- Predation is lowest in areas along the equator because of increased rates of decomposition.
- The corals need the strong water currents found here in order to find sufficient mates.

Answer:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

Explanation:

Answer:

F= m x a

force = mass x acceleration

Explanation:

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.

Based on the fgiven K_{a} values of the acids, the equilibrim concentrations of[tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex] is dtermined using ICE tables.

An acid dissociation constant, [tex]K_{a}[/tex] of an acid is a measure of the strength of the acid in solution. The larger the [tex]K_{a}[/tex] value of an acid, the stronger the acid, therefore, acid dissociation constants are usually apply to only weak acids because strong acids have exceedingly large [tex]K_{a}[/tex] values.

It is written as a  qoutient of the equilibrium concentrations of the aqueous species in the acid solution.

For the weak acids such as [tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex], their equilibrim concentrations are determined using their [tex]K_{a}[/tex] values and an ICE table.

The pH of solutions are estimated using indicators such as methyl orange, methyl red and phenolphthalein. The colors of indicators change according to the pH of the solution

Acidic solutions have pH less than 7 while alkaline solutions have pH greater than 7.

Therefore, acids have low pH and weak acids have low [tex]K_{a}[/tex] values.

Answer:

Sodium nitride is exothermic reaction and hydrochloric acid is endothermic reaction.

The mass of NH₃ : = 17.629 g

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Given

125 g NCl₃

Required

The mass of NH₃

Solution

mol NCl₃(molar mass : : 120.5 g/mol)

= 125 g : 120.5 g/mol

= 1.037

From the equation, mol ratio NCl₃ : NH₃ = 1 : 1, so mol NH₃ = 1.037

Mass NH₃(molar mass : 17 g/mol) :

= 1.037 x 17

= 17.629 g

Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

In physics, work is the energy transferred to or from an object via the application of force along a displacement.

In this problem, the force that does the work is the one that opposes the weight.

Solid Snake is 75 kg and is carrying 18 kg of equipment. The total mass is:

m = 75 kg + 18 kg = 93 kg

We can calculate the weight using Newton's second law of motion.

F = m . g = 93 kg . 9.8 m/s² = 911.4 N

Solid Snake climbs 27 flights of stairs, each 5.5 m in height.

27 . 5.5 m = 148.5 m

We will use the definition of work.

w = F . s = (911.4 N) . (148.5 m) . (1 kJ/1000 J) = 135.34 kJ

Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

Thermal energy flows from hot to colder bodies and is determined by the process of calorimetry.

Thermal energy is the energy transfer process which occurs as a result temperature difference between two bodies.

Thermal energy flows from hot to colder bodies.

The quantity of Heat transfer is determined using a calorimeter.

The calorimeter works on the principle of conservation of energy. The principle of the calorimeter is stated as follows:

The quantity of Heat, q = mass × specific heat capacity × temperature difference

Therefore, it can be concluded that thermal energy flows from hot to colder bodies.

The transition metals can form a variety of complexes because can lose as well as accept electrons .

The transition elements are those elements that are foud at the middle part of the periodic table having incompletely filled d orbitals.

The use of pomace for animal feed might be chosen if minimizing production costs is desired

Explanation:

i've taken the test

The use of pomace for animal feed might be chosen if minimizing production costs is desired. Therefore, the correct option is option D.

The solid byproduct of pressing grapes, olives, or even other fruits for juice or oil is known as pomace or marc. It includes the fruit's skins, pulp, seeds, or stems. Pomace brandy has traditionally been made from grape pomace. Currently, it is primarily used as fertilizer, animal feed, or to extract bioactive substances like polyphenols.

The Latin word "pomum" is where "pommace" comes from. The phrase "pomace" was first used by the English to describe the byproduct of making cider. Pomace wine, which had an alcohol concentration of three to four percent, was very common during the Middle Ages. The use of pomace for animal feed might be chosen if minimizing production costs is desired.

Therefore, the correct option is option D.
