How do seed plants protect their embryos?
Reptilian embryos are protected from desiccation by a leathery shell. Similarly, sporophytes of both gymnosperms and angiosperms protect embryos within, and they also protect male gametophytes against desiccation using .....

What is the symbol for an ion with 50 protons 48 electrons 68 neutrons?

Reptile [31]

Sn2+

Your protons equal the atomic number of an element: Sn (Tin).

The amount of protons and electrons will be the same if the atom is neutral. In this case, tin has lost two electrons and so tin is no longer neutral and becomes Sn2+

To double check, you would subtract the atomic number from the mass number of tin to see if the number of neutrons is equal to what has been provided.

mass number - atomic number = number of neutrons
118 - 50 = 68

Convert the following descriptions into balanced equations:

uysha [10]

Balanced equation for hydrogen gas is passed over powdered iron(III) oxide, iron metal and water vapor form.

$3H_{2(g)}+ Fe_2O_{3(s)}$ → $3H_2O_{(g)}+2Fe_{(s)}$

<h3>What is a balanced equation?</h3>

A balanced chemical equation is a chemist's shortcut for representing the molecules and atoms involved in a chemical process using chemical symbols. On the left side of the equation are the reactants, and on the right are the products. The number of molecules involved is indicated by the coefficients, and the number of atoms in each molecule is indicated by the subscripts.

Based on the interactions of the constituent chemicals, knowledge of the law of conservation of mass, and practise with a few example equations, chemical equations can be "balanced," much like algebraic equations.
