Answer:

Water

Weather

Explanation:

In an ecosystem, the factors that affect the organisms in that ecosystem can either be BIOTIC OR ABIOTIC. Biotic factors refers to the living components of an ecosystem while the ABIOTIC factors refer to the non-living components of the ecosystem.

According to this question, the abiotic (nonliving) factors that can affect a deer population includes WATER AND WEATHER. Note that the other options including flies and other organisms are both biotic factors.

Which chemical equation best represents the Law of Conservation of

astra-53 [7]

2H₂ + O₂ ⇒ 2H₂O

<h3>Further explanation</h3>

Conservation of mass states that

<em>In a closed system, the masses before and after the reaction are the same</em>

So it can be concluded

mass of the reactants = mass of the products

mass cannot be created or destroyed

The number of atoms involved in a reaction remains the same⇒ number of moles also the same
chemical equation in balanced form

So let's see which of the several options , which one has the same number of atoms on both sides of the equation

2H₂ + O₂ ⇒ 2H₂O

H ⇒ left 4, right 4

O ⇒ left 2, right 2

so the equation is in balance and represents the Law of Conservation of

3. What is the relationship between the kinetic energy of gas particles and the

vampirchik [111]

Answer:

The average kinetic energy of the particles in a gas is proportional to the temperature of the gas.

Explanation:

Because the mass of these particles is constant, the particles must move faster as the gas becomes warmer.

The map shows watersheds with a high potential for soil, nitrogen, and pesticide runoff. If you were in charge of handling the p

Yuri [45]

Answer:

Here are some possible answers:

Why are watersheds in the Midwest more prone to pollution in than other areas in the country?

What are the current flood and pollution control measures in place in high-risk regions?

What are the flaws with the systems used to control pollution in high-risk regions?

What can the officials and scientists in one region learn from those in another region?

What would the effects on residents be if we made changes to current flood and pollution control measures?

Explanation:

When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate.

What is the speed of the silver sphere at the moment it hits the ground? (Assume that energy is conserved during the fall and th

uranmaximum [27]

Complete question:

Consider the two spheres shown here, one made of silver and the other of aluminum. The spheres are dropped from a height of 2.1 m. (composition of sphere : density is 10.49 g/cm³, volume is 196 cm³), (composition of aluminum : density is 2.7 g/cm³, volume is 196 cm³).

What is the speed of the silver sphere at the moment it hits the ground? (Assume that energy is conserved during the fall and that 100% of the sphere’s initial potential energy is converted to kinetic energy by the time impact occurs.)

Answer:

The speed of the silver sphere at the moment it hits the ground is 6.416 m/s

Explanation:

Potential energy of the silver sphere = mgh

where;

g is acceleration due to gravity = 9.8 m/s²

h is height above the ground = 2.1m

m is mass of the silver sphere =?

Density = mass/volume

mass of the silver sphere = density X volume = (10.49 g/cm³) X (196cm³ )

mass of the silver sphere = 2056.04 g = 2.056 kg

Potential energy of the silver sphere = (2.056 X 9.8 X 2.1) J

Potential energy of the silver sphere = 42.31248 J

If energy is conserved and 100% potential energy is converted to kinetic energy, the speed of the silver sphere will be calculated as follows:

Kinetic Energy (K.E) = 1/2mv²

where;

m is mass of the sphere in kg = 2.056kg

v is the velocity of the silver sphere = ?

If energy is conserved; Potential energy = Kinetic energy

42.31248 = 1/2mv²

v² = (42.31248 X 2)/m

v² = (42.31248 X 2)/2.056

v² = 41.16

v = √41.16

v = 6.416 m/s

Therefore, the speed of the silver sphere at the moment it hits the ground is 6.416 m/s

What is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? Ass

Nataly [62]

Answer:

Ba^2+(aq) + 2OH-(aq) + 2H+(aq) + SO4^2-(aq) → BaSO4(s) + 2H2O(l)

Explanation:

Step 1: Data given

the contribution of protons from H2SO4 is near 100 %.

Step 2: The unbalanced equation

.Ba(OH)2(aq) + H2SO4(aq) → BaSO4(s) + H2O(l)

Step 3: Balancing the equation

On the left side we have 4x H (2x in Ba(OH)2 and 2x in H2SO4). On the right side, we have 2x H (in H2O).

To balance the amount of H on both sides, we have to muliply H2O (on the right side) by 2.

Ba(OH)2(aq) + H2SO4(aq) → BaSO4(s) + 2H2O(l)

Step 4: The net ionic equation

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will.

Ba^2+(aq) + 2OH-(aq) + 2H+(aq) + SO4^2-(aq) → BaSO4(s) + 2H2O(l)

After canceling those spectator ions in both side, look like this:

Ba^2+(aq) + 2OH-(aq) + 2H+(aq) + SO4^2-(aq) → BaSO4(s) + 2H2O(l)
