Explanation:
Elements in group fourteen are mostly known to form compounds in which there are four electron domains leading to a tetrahedral electron domain geometry.
However, the presence of lone pairs affects the shape of the molecule. SnCl3− has four electron domains, three of them are bond pairs while one is a lone pair. The shape of the molecule is based on a tetrahedron, however the observed geometry is trigonal pyramidal due to the presence of the lone pair. Its bond angle is now less than the predicted 109 degrees.
The answer is a. temperature and pH can affect how the enzymes work
Answer:
5.66g/ml
Explanation:
Mass of Metal Slug, m = 25.17g
Volume of container (flask), v = 59.7ml
Mass of Methanol, M = 43.7g with density, d = 0.791g/ml
Therefore,
Volume of Methanol = M/d = 43.7 / 0.791 = 55.25ml
Volume of Metal slug in the flask = v - V = 59.7 - 55.25 = 4.45ml
Density of Metal slug = mass of metal slug / volume of metal slug
= 25.17 / 4.45 = 5.66g/ml

the air you breathe is called carobon dioxide = co
Answer:
E = 3 × 10¹⁰ J
Explanation:
Mass, m = 100 kg
We need to find energy made by the loss of 100 kg of mass. The formula between the mass and energy is given by :
E = mc²
Where c is speed of light
Putting all the values, we get :
E = 100 kg × (3×10⁸ m/s)²
= 3 × 10¹⁰ J
So, the required energy is 3 × 10¹⁰ J.
