I'm pretty sure it's this
[Ar] 3d6 4s2
Atomic number: 26
symbol:Fe
Answer:Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
Explanation:
Answer:
Acceleration = (v Final −v Initial)/(t Final −t Initial). Where v stands for velocity and t stands for time. In algebraic notation, the formula can be expressed as: a=Δv/Δt; Acceleration can be defined as the rate of change of velocity with respect to time.
Answer:
c. 80 g
Explanation:
metal alloy:
- wt% = (mass compound/mass alloy)×100
for antimony:
⇒ 16% = (g antimony / g alloy)×100
⇒ 0.16 = g antimony / g alloy
∴ g alloy = 500 g
⇒ (0.16)×(500 g) = g antimony
⇒ g antimony = 80 g
