To find the acceleration, use the formula: force= mass x acceleration.
12.5 N = 10 x Acceleration
Acceleration = 12.5 / 10
Acceleration = 1.25
Hope this helps :)
Answer:
0.16 moles of Ar
Explanation:
One mole is equal to 6.022×10^23 atoms
9.63 x 10^22 atoms * 1 mol/6.022×10^23 atoms = 0.15991364995 moles
Answer:
D. As one variable increases, the other variable also increases
<span>1) The electron configuration of Re is [Xe] 4f14 5d5 6s2
</span>
<span>The ion Re (3+) has lost 3 electrons, so its configuration is </span><span>[Xe] 4f14 5d4
</span>
Then, the number outer-shell d electrons is 4.
<span>2) Sc: [Ar] 3d1 4s2
</span>
Sc (3+) has lost 3 electrons -> <span>[Ar] which has not d electrons.
</span>
<span>Then, the number of d electrons is 0</span>
<span>3) Ru: [Kr] 4d7 5s1
</span>
Ru (4+) has lost 4 electrons -> <span>[Kr] 4d4
</span>
Then, the number of outer-shell d electrons is 4
<span>4) Hg: [Xe] 4f14 5d10 6s2
</span>
Hg (2+) has lost 2 electrons -> <span>[Xe] 4f14 5d10
</span>
<span>Then, the number of outer-shell d electrons is 10</span>
Answer:
Strong Acid
Explanation:
ph 1 to 7 acidic 7 is neutral and onwards till 14 is alkali so in this case its ph is 2 which is a strong acidic
