On the right side, there are
• 2•2 = 4 atoms of Nb
• 2•5 = 10 atoms of O
so among the reactants on the left, the reaction is balanced as
4 Nb + 5 O₂ → 2 Nb₂O₅

Answer:
The probabilities would be 4/11 and 7/11 respectively.
Step-by-step explanation:
1) Total length of the given word i.e. Mathematics = 11
2) Number of vowels in the given word = 4 i.e. a,e,a,i
3) Number of consonants in the given word = 7 i.e. m,t,h,m,t,c,s
4) The probability of choosing a vowel would be 4/11 = 0.3636..
5) The probability of choosing a consonant would be 7/11 = 0.6363...
Step-by-step explanation:
