Answer:
Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup.
It is A , each sodium ion is surrounded by one chloride ion . the explanation is because Chlorine needs one more electron to have a full outer most shell , and sodium has one electron in its outer most shell .
Answer:
6 and 3
Explanation:
"Juanita begins to factor an expression as shown.
x² + 3x − 18 = (x + _) (x − _)
What numbers should be placed in the boxes from left to right?"
Use AC method to factor.
1 × -18 = -18
Factors of -18 that add up to 3 are +6 and -3.
The factors are x + 6 and x − 3.
When propane is burned in air in a process known as combustion it produce carbon (IV) oxide and water
the word equation is as follows,
propane + oxygen--->carbon (IV) oxide + water
chemical equation is as follows
2C3H8 +7O2---> 3CO2 + 8 H2O
hence 2 moles of propane reacted with 7 moles of oxygen to give 3 moles of CO2 and 8 moles of H2o
Answer: They are both non polar molecules compounds although water is a polar molecule compound. There are no significant attractions.
