Reaction B: sodium carbonate + hydrochloric acid → sodium chloride + carbon dioxide + water1 Na2CO3 (s) + 2 HCl (aq) → 2 NaCl (aq) + 1 CO2 (g) + 1 H2O (l)If 0.500 g of Na2CO3 and a slight excess of HCl react, how much NaCl will be produced? Using Cramer’s Rule, find the […]

What is the formula for magnesium hydroxide? How do you know when to use parentheses? I always get questions wrong cause I forget them.

Please explain (in 50-100 words), each type of diversification associated with Unrelated Diversification and provide an example. In addition, Please discuss (in 50-100 words) when would a company benefit from Unrelated Diversification. What is the difference between Reynolds analogy and the Chilton–Colburn analogy? Which is more useful?

In real life computation, we can only round irrational numbers to certain number of decimal places, such as pi =  3.141592654 and e = 2.718281828. If we round the numbers to five decimal places, we have π’ = 3.14159 and e’  = 2.71828. For any real number x, we round it up/down to five decimal

Light containing two different wavelengths passes through a diffraction grating with 1.20 x 103 slits/cm. On a screen 15.0 cmfrom the grating, the third – order maximum of the shorter wavelength falls midway between the central maximum and the first side maximum for the longer wavelength. If the neighboring maxima of the longer wavelength are 8.44

A galvanic cell is made from two half-cells. In the first, a platinum electrodeis immersed in a solution at pH 2.00 that is 0.100 M in both MnO4 − and Mn2+. In the second, a zinc electrode is immersed in a 0.0100 M solution of Zn(NO3)2. Calculate the cell voltage that will be measured. What does

Give the chemical formula for (a) chlorite ion, (b) chloride ion, (c) chlorate ion, (d) perchlorate ion, (e) hypochlorite ion. The cost of constructing an 8000 ft2 warehouse was $400,000. The ENR construction cost index was 6770 at that time. The cost of constructing a similar building using an ENR index of 9088 is closest to:

Why do you think epithelial tissue does not contain any blood vessels? Can you think of any epithelial function that could be compromised if blood vessels were running through the tissue? How is specificity to a substrate determined? find the exact value of cos(tan-1 (8/15)) Verify the identity:

A metalloid rod 2 cm in diameter is used as a heating element. The thermal conductivity is 370 J/s-m²-°C. The surface temperature is maintained at 200°C. For the center of the rod not to exceed 500°C, the maximum volumetric heat generation rate within the metallic rod in J/s-m³ must be
