Answer:

c) 40 (o), 35 (+), 34 (-)

Explanation:

Let us represent the element with P

Given information about the element:

Charge on P = +1

Mass number of P = 75

We can express the atom as ⁴⁵P¹⁺

The positive charge on the atom denotes that the atom has lost an electron. Electrons are negatively charge elementary particles in an atom. Therefore, the number of protons, positively charged particles are now more. This charge imbalance is what leaves atom P with a charge of +1. The difference between the proton number and number of electrons is just 1 and it represents a loss of an electron. Atoms that are not charged have their proton and electron number to be the same. Those that are negatively charge signifies that an electron has been gained and the number of electrons are greater than those of the protons.

The mass number 75 is the number of protons plus neutrons.

Option C gives the following information:

Neutron = 40

Protons = 35

Electrons = 34

Here Protons > Electrons with a difference of 1+.

Mass number  = Protons + Neutrons =35 + 40 = 75

We are given the amount of water for the electrolysis reaction. This will be the starting point of our calculation.

45.6 grams H2O (1 mol H2O / 18.02 g H2O) (1 mol O2 / 2 mol H2O) = 1.27 mol O2

10) The presence of nitrates in soil can be shown by warming the soil with
tresset_1 [31]

Answer:

ammonia

Explanation:

Nitrogen fertilizers contain N in the forms of ammonium, nitrate and urea. Upon application to the soil, urea-N rapidly hydrolyzes to ammonia, thus it shares similar characteristics as ammonia-based N fertilizers.
