Answer:
Na2B4O7 + H2SO4 + 5H2O → 4H3BO3 + Na2SO4
Explanation:
The unbalanced equation is given as;
Na2B4O7 + H2SO4(aq) + H2O → H3BO3(s) + Na2SO4(aq)
Balancing the equation of the reaction involves making sure the number of moles of elements in the reactants to be equal to the number of moles of the element of the products.
The balanced equation is given as;
Na2B4O7 + H2SO4 + 5H2O → 4H3BO3 + Na2SO4
Answer:
Yah, it's true.
because protons are represented as helium (²4He) which are positive.
electrons are represented as 0-1e which is negative
14 protons, a non-metal, a neutral carbon would have 4 valence electrons (don’t add things to do with its mass or charge, as it’s not finite)
Answer:
2
Explanation:
There are 3 carbons on the right side
there are only two on the left side....you need one more ...so add one more... change the '1' coefficient in front of C to '2'
