Fluorine since it is a halogen (non-metal), then it would need to bond with a metal in order to form an ionic bond.

Fluorine would therefore need an element from any of the metal groups to bond with in order to form an ionic compound e.g. Group One (Sodium or Lithium) or Group Two (Magnesium or Calcium) or Group Three (Aluminum) or a Transitional metal (Copper or Vanadium).

Which scenario supports the ""one gene–one enzyme"" hypothesis of metabolic disease causation?

damaskus [11]

The scenario that supports the "one gene-one enzyme" hypothesis of metabolic disease causation is Phenylketonuria (PKU). This disease (PKU) is caused by the failure to produce a functional variant of an enzyme.

Phenylketonuria (PKU) is a metabolic inherited disorder associated with a decreased metabolism of the amino acid phenylalanine.

PKU is caused by a mutation in the gene responsible for encoding a key enzyme needed to break down phenylalanine.

Untreated PKU may lead to diverse health problems which include brain damage, intellectual disability, seizures, mental disorders, etc.

What is the volume of 4.78g of O2 gas at STP?

My name is Ann [436]

Answer:

Explanation:

The trick here is to realize that if you know the volume of a gas at STP, you can use the fact that

mole of any ideal gas occupies

22.7 L

under STP conditions to calculate how many moles of gas you have in your sample.

Under STP conditions:

1 mole of an ideal gas = 22.7 L

−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−

In your case, you know that your sample of gas occupies

2.28 L

under STP conditions, which are currently defined as a pressure of

100 kPa

and a temperature of

∘

This means that your sample will contain

Now, the molar mass of the gas is the mass of exactly

Since this is the mass of

Urea makes up a significant amount of urine, and is the chemical that the body uses to rid cells of unwanted carbon dioxide and

Ira Lisetskai [31]

Urea is highly soluble in water. When it is allowed to dissolve in water in the presence of heat, it will yield ammonia and carbon dioxide. The reaction is shown below:

<span>NH2-CO-NH2 + H2O </span>⇒ 2 NH3 + CO2

As you can observe in the stoichiometric equations, 1 molecule of water can dissolve with 1 mole of urea.
