Protons have a positive charge, electrons are negative; say theres 5 protons and 5 electrons, those cancel each other out therefore it would be neutral or just no charge. If there is more protons then electrons then it would be a positive ion, if there is more electrons then protons then it would be a negative ion

What is the acceleration of a 200 gram ice cube if the<br> net force on the ice cube is 2 N?
Law Incorporation [45]
Net force = mass x acceleration so you would plug in the numbers to make it
2n = 200 x a then divide by 200 on both sides
A = 0.01 m/s

A student is trying to calculate the density of a ball. She already knows the mass, but she needs to determine the volume as wel
Reptile [31]
Let's examine the given choices:
V = (4/3)*pi*(r)^3 is the rule to calculate the volume of the sphere
V = (1/3)*pi*(r)^2*h is the rule to calculate the volume of the cone
V = s^3 is the rule to calculate volume of the cube
V = pi*(r)^2*h is the rule to calculate volume of the cylinder

Now, the ball can be treated as a perfect sphere, therefore, to calculate its volume we will use the rule of the volume of sphere.

Based on this, the correct choice is:
V = (4/3)*pi*(r)^3

The mass in grams of C in 275 g of C3H6
Furkat [3]

Answer:

Mass of carbon = 236.5 g

Explanation:

Given data:

Mass of C₃H₆ = 275 g

Mass of C = ?

Solution:

Formula:

Mass of carbon =  molar mass of carbon/ molar mass of compound × mass of compound

Molar mass of carbon = 12 g/mol

Molar mass of compound = 42 g/mol

Mass of carbon = 36 g/mol / 42 g/mol × 275 g

Mass of carbon = 0.86 × 275 g

Mass of carbon = 236.5 g
