can a chemical reaction take place without enzyme​

Answers

Answer:

Theoretically, Yes (See the explanation)

Explanation:

The body has enzymes that catalyze processes, as several other respondents have mentioned. I haven't noticed any comments, but the reverse impact might be just as significant. Some enzymes are reaction inhibitors. Others operate as both catalysts and inhibitors, depending on the amounts of the reactants and reaction products close to the catalyst. I'll provide an illustration to demonstrate how crucial inhibition may be. Let's say you consume three banana splits one after the other. That is a large number of calories. You would have a very high temperature and be so energetic and full of energy that you would be bouncing off the walls if all those calories were converted simultaneously into energy and heat. But neither you nor I have ever heard of overeating creating a high temperature or anxiety. This is due to the fact that many of the high energy molecules produced by the process hinder the enzymes that regulate metabolism, which produces the energy needed to power your body and generate heat. In other words, if you don't require high energy, your body won't keep making it. When there are huge amounts of carbohydrates around, the enzymes that turn the carbohydrates you consumed into glycogen and fat (to store the extra energy you don't need right now) become catalytic (mostly glucose). Therefore, the /majority of the energy from those three banana splits will be stored as fat and glycogen as it won't be needed. And that occurs as a result of the reaction to turn the sugars into energy being blocked by the lack of a demand for the energy at the time. Both enzymes that act as catalysts and those that act as inhibitors are essential to the healthy operation of our bodies.

Answers

Answer:

B.) +6

Explanation:

To find the oxidation number of sulfur, we can assume the oxidation numbers of the other elements.

What I mean is, oxygen (O) always has an oxidation number of (-2). That being said, if there are 4 oxygen atoms, oxygen is contributing -8 overall. We also know that hydrogen generally has an oxidation number of (+1). Like before, if there are 2 hydrogens, it must be contributing +2.

If the overall molecule is neutral, we have to get these charges to balance out.

In essence, -8 + 2 + ? = 0?

If you combine the charges from oxygen and hydrogen, you are left with -6. Therefore, to make the molecule neutral, sulfur must have an oxidation number of +6.

Answers

Although soils are capable of resisting pH changes, there are some circumstances where the pH of the water can result in alterations.

Will Soil pH Be Affected by Water pH?

The texture of soil affects how susceptible it is to the pH of the surrounding water. Smaller soil particles, such as clays and clay loams, have a greater impact than larger, sandier soils. There are more colloids, which are extremely minute particles, in fine-textured soils. Positively charged ions are maintained at these colloids. The cation exchange capacity of a soil refers to its capacity to hold onto these ions. Ions on the colloidal particles trade places with ions in the soil solution. The pH of the soil is less affected by negative ions in the soil solution.

Answers

Considering the definition of volume, the volume of the box is 30 mL or 0.03 L.

What is volume

Volume is a metric magnitude that is defined as the extension in three dimensions of a region of space. In other words, it is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.

Volume can be considered as the capacity of a container to hold a quantity of fluid (gas or liquid).

Volume of a box

A box is a rectangular prism, which is defined as a prism with rectangular bases and rectangular lateral faces.

The volume of this prism depends on its three dimensions and is calculated as the multiplication of these dimensions:

Volume= Dimension 1× Dimension 2× Dimension 3

Volume of the box in this case

In this case, you know that a box has dimensions of 2.5 cm by 3.0 cm by 4.0 cm. So, the volume can be calculated as:

Volume= 2.5 cm× 3 cm× 4 cm

Solving:

Volume= 30 cm³

Being 1 cm³=  1 mL and 1 L= 1,000 mL then:

Volume= 30 cm³= 30 mL= 0.03 L

Finally, the volume of the box is 30 mL or 0.03 L.

If 2 moles of water decomposes, the products that will form are 2 moles of hydrogen gas and one mole of oxygen gas. If a reaction is conducted that consumes 20.0 mL of water, what volume of oxygen gas will be produced

Answers

Answer:

Explanation:

The balanced equation for the decomposition of water is:

2H2O = 2H2 + 1O2

This tells us that we should expect 1 mole of O2 for every 2 moles of H2O, a molar ratio of (1 O2/2 H2O).

If we start with 2 moles of water, we should get (2mole H2O)*(1 O2/2 H2O) = 1 mole of H2.

But we are given just 20ml of water by the stingy boss.  We need to calculate the number of moles of water in that 20 ml.  We'll assume pure water at room temperature, so density = 1g/ml.  We have 20 g of H2O.  To find moles, divide by water's molar mass of 18 g/mole:

20g/(18g/mole) = 1.11 moles H2O

The moles of H2 produced would be:

(1.11 moles H2O)*(1 O2/2 H2O) = 0.55 moles O2 produced

We are not given the conditions of temperature and pressure, so the only way the calculate a volume of gas occupied by 1 mole of oxygen is to assume standard temperature and pressure (STP).  At STP 1 mole of gas occupies 22.4 liters.

1 mole of O2 will be 22.4 liters.

0.55 moles of O2 would be:

(0.55 mole O2)*(22.4 liters) = 12.32 liters

What type of bond is formed between the following elements/molecules (ionic, polar covalent, or nonpolar covalent)?

Answers

Answer:

1.) Ionic

2.) Nonpolar Covalent

3.) Polar Covalent

Explanation:

Ionic bonding generally occurs when a metal and nonmetal wish to donate/receive electrons from each other. These bonds are between two atoms with a large electronegativity difference. In the first diagram, potassium (K) is a metal and chlorine (Cl) is a nonmetal. As you can see, after the reaction, potassium donates an electron to chlorine.

Nonpolar covalent bonding occur when atoms of practically the same electronegativity combine. As such, atoms of the same nature have a zero electronegativity difference and thus always form these bonds.

Polar covalent bonding generally occurs between two nonmetals. These atoms have an intermediate size electronegativity difference. Carbon (C) and chlorine satisfy this rule.
