Which statement correctly explains whether or not this equation is a balanced equation? kmno4 + hcl → kcl + mncl2 + h2o + cl2
a. the equation is not balanced because the number of atoms of each element on the left is not equal to their numbers on the right.
b. the equation is not balanced because there are not any numbers in front of the compounds.
c. the equation is balanced because it has equal amounts of reactants and products.
d. the equation is balanced because it has one of each compound.

What is the polyatamic ion of borate

May someone me with these science questions

The table lists the lattice energies of some compounds.compoundlattice energy (kj/mol)lif            –1,036licl            –853naf            –923kf            –821nacl            –786which statement about crystal lattice energy is  best  supported by the information in the table? the lattice energy increases as cations get smaller, as shown by lif and kf.the lattice energy increases as the cations get larger, as shown by lif and licl.the lattice energy decreases as cations get smaller, as shown by nacl and naf.the lattice energy decreases as the cations get smaller, as shown by naf and kf.
