Answer:
a subatómica puedo relacionar el número atómico?
Explanation:
Answer:
7.506 g
Explanation:
In order to answer the first question we need to keep in mind the requested concentration of acetate: 0.250 M. With the concentration and the volume we can calculate the required moles and then the required grams:
0.250 M * 0.500 L = 0.125 moles acetate
0.125 moles * 60.05 g/mol = 7.506 g
So 7.506 g of acetic acid will be needed to prepare the buffer.
Oxygen is more electronegative than boron. It has more tendency to attract a electron pair while boron is electropositive that means it has more tendency to lose an electron so when there will be a bond between boron and oxygen than boron carries the partial positive charge while oxygen carries the partial negative charge.
Answer:
a) Balanced equation
3NH₄Cl (aq) + Na₃PO₄ (aq) → 3NaCl (s) + (NH₄)₃PO₄ (aq)
b) Total Ionic Equation
3NH₄⁺(aq) + 3Cl⁻(aq) + 3Na⁺(aq) + PO₄³⁻(aq) → 3NaCl(s) + 3NH₄⁺(aq) + PO₄³⁻(aq)
c) Net Ionic Equation
3Cl⁻(aq) + 3Na⁺(aq) → 3NaCl (s)
Answer:
science is nothing without funding
Explanation:
Well Science in the US is highly a political affair. Scientists need funding for research, so they usually have to obtain grants from people who have the means to spare it. In many cases that means people who are involved with the government, or have close ties to it.
So scientists find themselves having to play off partisan politics in order to secure the funding they need for their research. Many times they also find that their research will inevitably get skewn to meet the original funders own ends.
Mostly what I have said is commonly known. However I am in school, and deal with scientists and doctoral researchers who have expressed and validated similar experiences.
