Answer:

Explanation:

4 atoms would be produced, since the reactants are 2 atoms of magnesium and 1 molecule of diatomic oxygen (which contains 2 atoms). Due to the law of conservation of matter, the total number of atoms can not increase or decrease in a chemical reaction.

4 atoms

Explanation:

On the product side, we expect to find 4 atoms of the product.

An atom is the smallest indivisible particle that takes part in a chemical reaction.

An element is a distinct substance that cannot be split-up into simpler substances. Such substances consist of only one kind of atom.

In this reaction we have:

2 elements: Mg O

on the reactant side:

We have two moles of Mg: 2 atoms of Mg

1 mole of oxygen gas: 2 atoms of O

total atoms: 4 atoms

According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed".

We expect to find 4 atoms of products which is MgO on the product side.

2Mg + O₂ → 2MgO + heat

Consider the following four objects: a hoop, a solid sphere, a flat disk, a hollow sphere. Each of the objects has mass M and ra

Svetlanka [38]

Answer:

Hoop.

Explanation:

The angular acceleration performed at a given torque:

$\alpha = \frac{\tau}{I}$

The moments of inertia of each element are described below:

Hoop

$I = M\cdot R^{2}$

Solid sphere

$I = \frac{2}{5}\cdot M \cdot R^{2}$

Flat disk

$I = \frac{1}{2}\cdot M \cdot R^{2}$

Hollow sphere

$I = \frac{2}{3}\cdot M \cdot R^{2}$

The greater the moment of inertia, the greater the torque to obtain the same angular acceleration. Therefore, the hoop requires the largest torque to receive the same angular acceleration.

sports photographers often use large aperture, long focal length lenses. what limitations do these lenses impose on the photogra

Brut [27]

Answer:

The depth of focus achievable with those lenses is small.

Explanation:

A larger aperture makes it much harder to focus on more than one object. When using a telephoto lens (the ones the question is referring to), the depth of focus is very small. For example, using a telephoto lens to take a photo of a runner might get the runner in focus, but certainly not the track, or the audience behind them. If you look at photos, especially older photos, of Olympians in almost any sport you can see this.

Hope this helps!
