There are many simple ways to prevent erosion. One of the simplest forms of preventing erosion is with vegetation and by establishing root systems that hold the soil together. You can also use geotextiles, fertilizers and also build retainer walls to keep the soil intact and prevent erosion.

Which of the following is not the same as 5.63 grams? 5,630 mg 0.563 hg 0.00563 kg

Lady bird [3.3K]

Units of measure is defined as a the magnitude of a certain quantity. There are a lot of units that we can use for mass. Kilograms, grams, tons, pounds and slugs are some of the examples. There are some units where certain prefixes changes its magnitude. One thousand grams is one kilogram. One thousand mg is one gram. 5.63 grams is 5,630 mg and 0.00563 kg is 5.63 grams. Hence the answer here is 0.563 hg.

All compounds of carbon are made by _____.

Andrew [12]

Answer:

Covalent bonding

Explanation:

Covalent bonding is the bond that holds all compound that are formed by carbon.

It is a very strong intermolecular bond that holds the structure of carbon compounds in place.

Principally, covalent compounds are formed by sharing of electrons between contributing atoms.

Covalent bonds are the strongest bond types. A reason for this conclusion can be see in case of diamond. Here, there is a covalent linkage between the atoms present and the strength of these bonds is responsible for how strong the diamond crystal is

The rate law for the rearrangement of ch3nc to ch3cn at 800 k is rate = (1300 s-1)[ch3nc]. what is the half-life for this reacti

Lana71 [14]

The rate of reaction is always expressed in concentration per time like mol/L·s. The equation is:

r [mol/L·s] = kCⁿ, where n is the order of reaction. Since k is 1300/s, that means that Cⁿ = C such that (1/s)*(mol/L) = mol/L·s. Thus, n=1. For a first order reaction, the formula would be:

ln(A/A₀) = -kt
where
A is the amount of material after time t
A₀ is the amount of material at t=0

The half life is when A/A₀ = 1/2÷1 = 1/2. Thus, the half-life t is:

ln(1/2) = (-1300t)
t = 5.33×10⁻⁴ seconds

The equilibrium constant for the reaction NO2(g)+NO3(g)→N2O5(g) is 2.1x10-20 , therefore: a. At equilibrium, the concentration

frutty [35]

Answer: c. At equilibrium, the concentration of reactants is greater than the products

Explanation:

Equilibrium constant for a reaction is the ratio of concentration of products to the concentration of reactants each raised to the power its stoichiometric coefficients.

For the reaction:

$NO_2(g)+NO_3(g)\rightleftharpoons N_2O_5(g)$

Equilibrium constant is given as:

$K_{eq}=\frac{[N_2O_5]}{[NO_2]\times [NO_3]}$

$2.1\times 10^{-20}=\frac{[N_2O_5]}{[NO_2]\times [NO_3]}$

When

a) K > 1, the concentration of products is greater than the concentration of reactants

b) K < 1, the concentration of reactants is greater than the concentration of products

c) K= 1, the reaction is at equilibrium, the concentration of reactants is equal to the concentration of products

Thus as $K_{eq}$ is $2.1\times 10^{-20}$ which is less than 1,

the concentration of reactants is greater than the concentration of products
