You are looking at two samples of iron. One sample is very small and came from the red soil on the planet Mars. The other sample is very large and came from Earth's core. True or False, these two samples contain different atoms

In the early 1900s many scientists thought that an atom consisted of a positive substance with negative charges scattered throughout the substance. Then Ernest Rutherford made a discovery that led to the understanding that an atom consists mostly of empty space with- * 20 points A. protons orbiting a dense nucleus made of electrons and neutrons B. Neutrons and protons orbiting a cloud of electrons C. Electrons and protons orbiting a cloud of neutrons D. Electrons orbiting a dense nucleus made of protons and neutrons

A student combined equal amounts of two solutions. One solution had a pH of 2 and the other had a pH of 12. Which would most likely be the resulting pH? 1 3 6 11

Obi is trying to determine if a powdery, solid substance is an element or a compound. After recording some observations, he strongly heats a sample of the solid over a burner flame. After fifteen minutes, he turns off the flame and allows the sample to cool. He records his final observations in the data table.

A 3-column table with 3 rows. The first column labeled observation has entries appearance, mass (g), chemical reaction with weak acid. The second column labeled original sample has entries white solid, 100.0, bubbles. The third column labeled sample after heating has entries white solid, 56.0, no bubbles.
Which is the best explanation of his results?

A. The heating changed some of the sample to gas, causing the mass to decrease without breaking down the sample. Therefore, the original sample is a compound.

B. The appearance stayed the same, showing that the sample was not broken down by heating. Therefore, the original substance is an element.

C. The mass decreased during heating and some of the impurities escaped. Therefore, the original substance is an element.

D. The chemical reaction with acid changed, showing that the sample was broken down by heating. Therefore, the original substance is a compound.

What is the chemical symbol for table salt?

SCIENCE!! i need help on the question in the middle please!!!

Please help me identify the element. The picture is blurry so..
