Answer:
substituting unsaturated fats—like those found in olive oil—for saturated fats could lower your chance of developing heart disease.
Answer:
scientists have managed to capture atoms in the act of forming and breaking bonds, using transmission electron microscopy (TEM). In TEM imaging, a high energy beam of electrons is used to visualize a surface and create an impression of it digitally.

Answer: the answer is 0.32 meters but
Explanation: The prefix “centi-” means “one-hundredth,” so a centimeter equates to 1/100 of a meter. This means that converting from centimeters to meters always involves dividing by 100. Similarly, converting from meters to centimeters always involves multiplying by 100. hope it helps:)
Answer:
ΔH = + 116 kJ
Explanation:
The equation for the reaction is given as;
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) ΔH = - 58 kJ
If we multiply the above equation all through with (2); we have:
2 × (HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) ΔH = - 58 kJ)
2HCl(aq) + 2NaOH(aq) → 2NaCl(aq) + 2H2O(l) ΔH = - 116 kJ
If we tend to reverse the above equation; we have
2NaCl(aq) + 2H2O(l) → 2HCl(aq) + 2NaOH(aq) ΔH = + 116 kJ
∴ The reaction is said to be endothermin , as 116 kJ are absorbed.
Answer: 3.5 moles
Explanation:
For every 2 moles of sulfur consumed, there are 3 moles of oxygen consumed.
This means that sulfur is the limiting reactant, meaning that 2(3)=6 moles of oxygen will be consumed.
Thus, 9.5-6=3.5 moles of oxygen will remain.
