Mg + 2 HCl ------> MgCl₂ +H₂O
Answer:
Scientific Law
Explanation: Earth will ALWAYS attract objects to the center of itself because of gravity. This will never be disproven.
Answer:
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Calcium phosphide (CP) is the inorganic compound with the formula Ca3P2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca2+ and P3−.

Answer:
5528 balloons
Explanation:
Explanation:
At constant pressure and number of moles, using Boyle's law
Given ,
V₁ = 155.0 L
V₂ = ?
P₁ = 1835 psi
P₂ = 1 atm = 14.7 psia
Using above equation as:
Volume of each balloon = 3.5 L
Thus, number of balloons,
Answer:
The compound elucidated from the spectral data is <u>4-methyl penta-2-none</u>
Explanation:
- <u>1700 cm-1 from IR data</u> suspects aldehyde/ketone or carboxylic acid. However,since the peak is not a stretched vibration, it implies an aldehyde or ketone present.
- <u>3 ppm H NMR</u> confirms O-CH3 bond
- <u>24.4 13C NMR</u> confirms CH3-R bond
- 26.4 13C NMR confirms H3C-(R)C(H)-R
- 44.2 13C NMR Confirms C=
- 2126 13C NMR confirms aldehyde C=O bond
<u>The deduced structure is 4-methyl penta-2-one (see attached) </u>given multiple CH3 atoms.
